These are methods for subsetting mcmc objects. You can select iterations using the first dimension and variables using the second dimension. Selecting iterations will return a vector or matrix, not an mcmc object. If you want to do row-subsetting of an mcmc object and preserve its dimensions, use the window function.

Subsetting applied to an mcmc.list object will simultaneously affect all the parallel chains in the object.

# S3 method for class 'mcmc'
x[i, j, drop = missing(i)]
# S3 method for class 'mcmc.list'
x[i, j, drop = TRUE]

Arguments

x

An mcmc object

i

Row to extract

j

Column to extract

drop

if TRUE, the redundant dimensions are dropped
